ARM-CHAIR.

To all whom it may concern Be it known that I, ALBERT WANNER, J12, a citizen of the United States, residing at Hoboken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Arm- Chairs, of which the following is a specification.

This invention relates to chairs and it has for its object to provide an arm structure for chairs which may be adapted to chairs differing from each other in respect to the angular relation of the back and seat portions thereof and which will nevertheless in all instances be a rigid and firm adjunct of the chair, substantially proof against working loose.

The improved arm structure is illustrated in the accompanying drawings in connection with chairs of the bent-wood type, to which it is most suitably adapted, although it may be applied to other chairs.

In Figures 1 and 2 the arm structure is shown applied to chairs whose backs are inclined rearwardly at different angles, each view being a side elevation in which the chair appears in dotted outline; in Figs. 3 and 4 the arm structure and a part of the chair appear in front and rear perspective; and, in Fig. 5 the arm structure appears in plan, a part of the chair being shown in dotted outline.

The improved arm structure comprises the substantially C-shaped support a and the arm 6 with means for securing these parts together. The support a is preferably a piece of bent-wood bent into the form shown; that is, in addition to appearing Q-shaped in side elevation, its rear portion 0 is bent inwardly, as seen in the plan view, Fig. 5. The arm I) may be and preferably is formed of wood, being substantially straight in side elevation but curved in plan, its rearward end sweeping inwardly and following more or less the inward curving seen in the plan of the support a; the rearward extremity of the arm is tapered, as at (Z. The upper extremity e of the support, which is straight, has an elongated contact with the flat under side of the arm, to which it is secured by the screws f.

Arm structures of the kind above described may be made up in any desired quan tity, all alike, and when so made up any arm structure, without change in the relation of the arm and support portions thereof, may

be applied to any of a lot of chairs differing from each other in various respects as will now be indicated and yet in each instance the desired result of rigidity and strength will accrue.

In Figs. 1 and 2 two chairs are shown in dotted outline which differ from each other in that the back 9 of the chair in Fig. 1 inclines rearwardly appreciably more than that in Fig. 2. The arm, it should be remarked, is assembled with the chair by two screws 71. securing the back portion of its support Z) to the chair back at one side thereof and by two other screws 2' securing its lower extremity of said support flatwise against the side of the seat j of the chair, while, a proper hole it being drilled into the back 9, the tapered end of arm 6 is fitted or doweled into said hole and there secured by a screw Z entered through the back into the arm Z) lengthwise thereof, as shown in Fig. 4t. The difference between the angles of inclination of the backs of the chairs in Figs. 1 and 2 is a practically appreciable one, but it may be even greater. Thus, when the arm is to be secured to the chair the workman finds that point in the back where the hole for the tapered part (Z of the arm should be drilled in order to bring the back-portion of the support a and its lower extremity in proper relation to the chair back and seat, respectively. In a chair having its back in clined as much as is shown in Fig. 1, this point will be lower than in a chair whose back is inclined only as m nch as in Fig. 2. By reference to the dot and dash lines w-w in these two figures it will be obvious that the adjustment of the arm structure to chairs differing in the respect indicated is substantially one involving the shifting of the structure, one way or the other, around a point somewhere in the space outlined by the sup port a, and yet, when the operation of adjusting the arm structures and securing them to the chairs is completed, all the chairs will present uniform strength and rigidity. This quality, it will be further noted, does not appertain to the arm structure alone: while the arm structure is itself rigidly held because of being secured at three points it at the same time greatly reinforces the joint or joints between the seat and back, usually the point of greatest weakness. Chairs also differ from each other in other respects than that involving the inclination of the backs, of course. Thus, the backs may vary in width, the surfaces of the backs against which the arm structure is to be secured may be either rounded, angular or flat. In all these instances the improved arm structure may be secured in place with uniformly good results in the way indicated by simply drilling the hole is wherever it should go in order to accomplish attachment of the arm structure to the chair at the three points already designated regardless of the character of the surface into which the hole is to be drilled.

The improved arm structure is adapted, as will be obvious, to be applied to a large Variety of chairs notwithstanding all these structural diflerences which are prohibitive of the attainment of universally successful results in the matter of strength and rigidity in arm structures commonly employed.

A further advantage of the improved arm structure is that, on account of the C-shaped form of the support a ample hip-room is afforded. Again, the arm structure is suitable from the esthetic standpoint for use in a large variety of chairs differing from each other more or less in the matter of design.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. An arm structure for chairs comprising a substantially C-shaped forwardly open support and an arm, said arm being secured flatwise upon and extending longitudinally of the upper end of the support and having its rear end tapered and adapted to be doweled into the back of the chair, substanq tially as described.

2. In combination, with a chair including a back and a seat, an arm structure therefor comprising a substantially C-shaped forwardly open support and an arm, said arm being secured flatwise against and extending longitudinally of the upper end of the support and having its rear end tapered and doweled into the back of the chair, and said supporthaving its rear portion secured to the said back and its lower end secured fiatwise against the seat, substantially as described.

3. In combination, with a chair including a back and a seat, an arm structure therefor comprising a substantially C-shaped forwardly open support and an arm, said arm being secured flatwise against and extending longitudinally of the upper end of the support and having its rear end tapered and doweled into the back of the chair, and said support having its rear portion secured to the said back and its lower end secured fiatwise against the seat, and a headed securing device driven through the back into the tapered end of said arm, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
